Benefits of technology
The heat sink of the present invention extracts excess energy from the speaker motor structure and dissipates that energy in the form of heat into the surrounding air. This enables the speaker voice coil to perform within the normal / safe operating temperature and allows for greater power handling capabilities. The heat sink also increases the mechanical strength of the motor structure, increasing speaker life and ensures that the motor structure will not deform or shift maintaining the motor structure components in alignment.
Problems solved by technology
In addition, the initial ambient temperature of the speaker's motor structure in the trunk of a dark colored vehicle, when the outside temperature is in excess of 100.degree. F., may exceed 160.degree. F., another factor that can damage the speaker.
However, the heat dissipation occurs at a relatively slow rate.

Embodiment Construction
Referring now to FIG. 1, a perspective view of a commercially available speaker 10 in which the heat sink of the present invention is adapted for use is illustrated. The specific design of speaker 10 is disclosed in copending application Ser. No. 10 / 021488, filed Oct. 22, 2001, entitled "Improved Vehicle Speaker" and assigned to the assignee of the present invention. The teachings of the aforementioned application necessary for an understanding of the invention are incorporated herein by reference.
Speaker 10 includes an upper portion 12, commonly referred to as a motor structure, which incorporates a top plate 13, bottom plate (or T-yoke) 15, magnet(s) 17 and a voice coil (not shown) positioned adjacent diaphragm support 14. The bottom flange member 16 of support 14 has a plurality of fastening holes 18 formed therein.
Referring now to FIGS. 2-5, a first embodiment of the heat sink 30 of the present invention is illustrated.

A heat sink for dissipating the heat generated by a loudspeaker voice coil. The heat sink comprises a multi-piece, aluminum based structure bolted together and which encompasses the speaker motor structure. In a first embodiment, the heat sink comprises a plurality of spaced apart and separate, concentric disk shaped ring members, formed in segments, each segment being fastened together. In a second embodiment, the heat sink comprises a plurality of concentric disk shaped ring members formed in segments, each segment being fastened together. In each embodiment, the assembled heat sink is positioned over the speaker motor structures. The heat sink extracts excess energy from the speaker motor structure and dissipates that energy in the form of heat into the surrounding air enabling the speaker voice coil to perform within the normal / safe operating temperature and allows for greater handling capabilities. The heat sink also increases the mechanical strength of the motor structure, increasing speaker life and ensures that the motor structure will not deform or shift maintaining the motor structure components in alignment.
Description
1. Field of the InventionThe present invention provides a heat sink that encompasses a speaker magnet structure in order to dissipate heat energy into the surrounding air.2. Description of the Prior ArtModern day vehicle audio systems incorporate amplifiers (usually positioned in the trunk of the vehicle) that typically produce in excess of 1000 watts RMS (or continuous) power which, when applied to a voice coil of a woofer, or speaker, produces large amounts of heat. This heat is capable of melting the voice coil wire if the heat is not extracted and dissipated. In addition, the initial ambient temperature of the speaker's motor structure in the trunk of a dark colored vehicle, when the outside temperature is in excess of 100.degree. F., may exceed 160.degree. F., another factor that can damage the speaker.Conventional speakers utilize the dense composite ferrite material of the magnet structure and the steel top plate and T-Yoke of the speaker to dissipate the generated heat.
